The aim of this study was to examine the association between individual measures of internal training load (training impulse [TRIMPi]) and aerobic-fitness and performance variables in premiership male soccer players. Eighteen Premiership soccer players (age 28.4 ± 3.2 years, height 182 ± 5.3 cm, body mass 79.9 ± 5.5 kg) performed treadmill tests for VO(2max) and ventilatory threshold (VT) and speed at blood-lactate concentration of 4 mmol·L(-1) (S4) on separate days pre and post 8 weeks of training (preseason). The Yo-Yo Intermittent recovery test (Yo-Yo IR1) performance was assessed pre and post preseason training as well. The TRIMPi was calculated using individual lactate and heart-rate profiles and assessed in each training session (n = 900). The results showed that TRIMPi was large to very-large associated with percentage changes in VO(2max) (r = 0.77, p = 0.002), VT (r = 0.78, p = 0.002), S4 (r = 0.64, p = 0.004), and Yo-Yo IR1 performance (r = 0.69, p = 0.009). Regression analyses showed that a weekly TRIMPi >500 AU was necessary to warrant improvements in aerobic fitness and performance in premiership male soccer players during the precompetitive season. It is concluded that TRIMPi is a valid and viable tool to guide training prescription in male premiership soccer players during the preseason.
本研究旨在探讨个体内部训练负荷测量值（训练冲动[TRIMPi]）与有氧能力和表现变量之间的关系，研究对象为英超男性足球运动员。18 名英超足球运动员（年龄 28.4 ± 3.2 岁，身高 182 ± 5.3cm，体重 79.9 ± 5.5kg）分别在赛季前和 8 周训练后进行了跑步机测试，以测量最大摄氧量（VO2max）和通气阈值（VT）以及血乳酸浓度为 4mmol·L(-1)时的速度（S4）。在赛季前训练前后还评估了 Yo-Yo 间歇性恢复测试（Yo-Yo IR1）的表现。TRIMPi 使用个体的乳酸和心率曲线进行计算，并在每次训练中进行评估（n = 900）。结果表明，TRIMPi 与 VO2max（r = 0.77，p = 0.002）、VT（r = 0.78，p = 0.002）、S4（r = 0.64，p = 0.004）和 Yo-Yo IR1 表现（r = 0.69，p = 0.009）的变化百分比呈高度相关。回归分析表明，在竞争赛季前，英超男性足球运动员每周的 TRIMPi >500AU 是有氧能力和表现改善所必需的。因此，TRIMPi 是一种有效的工具，可以在赛季前指导男性英超足球运动员的训练方案。
